Student program

Rexus Bexus is a bilateral German-Swedish cooperation to offer students experiment opportunities using sounding rocket and balloon flights from Esrange Space Center in Northern Sweden.

German students have the opportunity to utilise half of the joint program pay load. Sweden has invited ESA Education to use most of the Swedish share for a European-wide program.

REXUS experiments are usually launched from Esrange on a rocket powered by an Improved Orion Motor with 290 kg of propellant. It is capable of taking 40 kg of student experiment modules to an altitude of approximately 100 km.

BEXUS experiments are lifted by balloon from Esrange to an altitude of 20-35 km, depending on total experiment mass (40-100 kg). The balloon has a volume of 12 000 m3 and the experiments are hanging 65-100 m below the balloon.
